To all whom it may concern:

Be it. known that. we, lsax Hausnr, Cani. and Abou' Dusar, citizens of the United Sta residing at Kansas City, in the county of ockeon and State of liliasouri, have invented certain new and useful rImprovements in Slices, of which the following is s specification.

Our invention relates to impioven'ieiits m shoes.

The object of our invention is to provide in n shoe a novel, resilient, foot support which will enable the wearer of the shoe to walk easily and with n springy step.

A further object of our invention is to provide s bellows'like footsupport, provided with menne by which, during the operation of walking. the nir within a shoe containing the sap rt may be ke t in constant circulation, t ereby facilitating evaporation and ailding to the comfort of the wearer of the s oc.

Other novel features are hereinafter fully dea-.ribed and claimed.

In the accompanying drawings which illustrate the preferred form of our invention, Figure 1 is a view, partly in elevation and partlyl in central vertical section, of a. shoe rovided ywith our improved foot support..

im 2 is a bottoni view, with the lower half of the sole and the heel removed. Fig. :l is a top view, with the upper removed.

Similar characters otl 'reference denote similar parts.

l denotes an ordinal shoe, having' a sole Qand the heel 3. A resi ient. su )port for the foot. is inoulited on the sole J a ove tbe heel 3. a bellows-like air pump, which is emilio-esci ble by the weight of the persons foot and is preferably provided wiih resilient mean.` for resisting such compression. The bellow- 'l`hi.-' foot support comprises pirferably Y case, as in winter time,

like suiport is preferably provided with j means or taking air from and projecting it into the interior of the shoe for the. iurpo-o 5 of causing a circulation of air uit iin the shoe. f

in the preferred form ot' oui' intention.

the bellows-like sup )ort is provided with a cu Shaped base 4. oi'ated in a verge-s provii ed in the u per side of the sole L', pret'- eralily ahovetlie heel 2. .\liove the hase l is a foot apport .-omprising' a horizontal plate :'i, which is preferably supported upon the upper end of a i-oil spring t, the lower side of the bottom of the cup-sha d member or base 4. T he ower end of tie spring ti is provided with projection 6', which extends vcrtically downward through an opening 7 provided tlieiefor in the bottom of the hase -l, the projection 6 hein turned laterally below the base 4, as shown in Fig. 2. A tiexible, tabular, air-tight member 8, which ma bc composed of any suitable inatcriil, suc i as soft rubber, oil cloth or plain canvas, is secured at its upper end to the foot support 5. The lower end of the meinber 8 is preferably detachably secured to the base 4, y means of two concentric rings 9 and l0 between which the tubular member 8 is tightly clamped, the ring 1t) being internnlly screw threaded uml fitted to the externally threaded periphery of the circular upper end of the base 4. By providing a resilient tubular member 8, composed of such material as soft, rubber, the s )rin r 6, if desired, may be dispensed wit ly having the member detachable fi'oiii the base l, said member ma be removed for any dcsired purpose. ior example to replace the spring 6 or to close the air conductor dispense with the air currents, and employ the mechanism solely as a resilient foot. suport. p A further object in having the foot eupport 5 and flexible member 8 detachable, is to permit their removal and that of the prmg l when the heel is compressed in the mishing of the shoe, or when it is desired to hammer the heel wi'thont injury to the spring or foot support.

'l'lobase l is provided with one or moi'e nozzles or air conductors ll. which are preferably embedded in the sole il. and are respectively provided willi outer open ends' l! which communicate with the interior of the hoc. :doive the ole L. 'l`ho openings l1! iii:i \l ladspowd wherever i't may he desired.

i t i 1 ln the draivingrv three v-iuh opening are Vdiown, two being loeated near the toe ol' the l-boe and one near the middle thereof.

In the operation of ont' invention, tlu` weight of'the foot moves 'the foot support downwardly. i-'iu'h movement being resisted by the priiipr (i, which. when the weight is removed. restores the l'oot support 5, to the elevated bositioii shown in li`ir. l. When the lsupport. ."i is de irri-wed the air is expelled from the bellowsike support into the inend of which is supported upon the upper terior ot' the shoe through the nozzles or il in it may be desired to lOll , emular-tors ll. When the sprinpr t3 ruiws "'shoe.

the support .'i the air is drawn from the interior of the hoe through the said conditi-tera or nozzles, into the hellown-lilae te eeiier. By thil nir-aua, during walking the nir in the shoe will be kept in eon. tant eirrulation. thu farilitating-; the evaporation ofl tnoi-ture and prmhaing' a fooling etleet. upon the foot ol' he pet-.son wearing the y rearuu nl' the reailietu'y ol.' tlubellowlilte support. the person wearing the'ahoe will be enabled to walk easily and u ith a r irme) step, and the :ln-elm produced by tie striking of the heel ot the hhoe n mn I hard ground or pavement. will he absorbed and will not ntl'ecl the person. By having the conditi-tors terminating at their ildtaice and discharge end. above the wie of the shoe f und in eotnniunieation with the imi-rior thereof, there. is no opportunity ati'orded for water havin" actress from the exterior to the interior of tie .shoe through surh air rondoctors.

Various tnoditieatismx ol' our invention. within the scope of the appended elaim.-, muy be made without departing from it spirit.

Having thu-described ourlnventon, what we claim and desire to .secure by Letters lat` ent is':-

l. In a, `shoe, the emahinatiun with the sole, of a eirrnlar member huilt in said l ole and having one or more :tir wtasages roue niunieating with the interior f 'the shoe through said solo, and haring a screw i threaded up ier end, a spriir located in and detachable ront said mein l', and a foot .supportidg inverted cup shaped deviee restl ing upon said s ring,l and havin its lower end screw threat ed and detuehab y ltted to l the threaded portion of the circular member, the side walls of said device being tiexible.

L. in a dior, the roiuhiuation with the sole; of a cup shaped member embedded in hole, of a cup --shaped member embedded in mid .sole above the heel of the shoe. and haring a screw threaded up er end dispoeed below the upper side of t le sole. and having one or more air passages comnntnirating with the interior of the shoe through the wie, a coil spring located retnorabl in said cup ldiaped member, a llexible tubn ar member, a t'oot support resting on the said spring and secured to the upper end of `waid tlexible member, and two rmiza between whirh the lower end of the tlexible member is clamped, one of said rings being crew threaded und detaehably litted to 'the threaded upper end ol' the en i shaped member.

ln testimony whereof we have signed our nana-s te this speeilieation in presence of two subscribing witnesses.
